Thank you for reporting. A couple of archiving issues are fixed in the meantime. Please try with the nightly build to see if your issue is fixed.

https://kdenlive.org/en/download/ -> scroll down and choose standalone version for testing.

Version 21.04.3 still generates a corrupt zip archive file (Win10)

Comment 3 emohr 2021-07-23 14:37:39 UTC

Zip version was updated in the package lately (on Win7 it works). Please test with tomorrow's nightly build if the backup zip file is still corrupt: https://binary-factory.kde.org/job/Kdenlive_Nightly_mingw64/

Comment 4 Arno Rog 2021-07-27 10:37:32 UTC

Tested with nightly build 21.11.70
(Non blocking) errors while extracting tar or zip (using 7zip 64bit)
zip: 'Warning: 32-bit overflow in headers'
tar: 'unexpected end of data'

kdiff does not show any difference in the extracted files

So you are saying with the daily build it works beside the warnings? Nevertheless can you upload here a small backup zip-file which "contains" the error?

Comment 6 Arno Rog 2021-08-02 10:07:06 UTC

I'm trying to reproduce the error with freely available video and audio files, but to no avail (even projects larger than 1 GB archive correctly).
My projects are usually larger than 5 GB.
Since I'm unable to help, (the problem is not solved) I'll close the story and make my archives uncompressed and compress them later.

Thank you for the feedback. Yes this is a good workaround.
